Solution

1. Preparation

Gather necessary tools:
- Wrench or socket set for battery terminal
- Safety gloves
- Safety glasses
Ensure the vehicle is in a safe area to work on.

2. Disconnect Battery

Using the wrench or socket, loosen the nut on the negative battery terminal.
Remove the negative cable from the battery terminal and ensure it is isolated to prevent accidental reconnection.

3. Wait for Residual Power to Discharge

Allow the vehicle to sit for at least 10 minutes. This time is necessary for any capacitors in the system to discharge fully.

4. Reconnect Battery

Reattach the negative battery terminal securely.
Tighten the nut to ensure a good connection, but do not overtighten to avoid damaging the terminal.

5. Start Engine and Let Idle

Start the engine and allow it to idle for approximately 5 minutes. This will enable the TCM to recalibrate its parameters.
Observe for any unusual sounds or warning lights during idle.
